Abstract: A cargo deck includes a floor engageable with a load. The floor is formed from extruded aluminum in tubular panels extending transversely along the floor. Side rails are disposed on opposed sides of the deck. A plurality of longitudinally-extending support members support the floor, and are coupled to the floor via a plurality of support brackets extending angularly from the floor to the support members.

Abstract: A trailer includes a floor engageable with a load, the trailer floor comprising a plurality of floor panels. Each floor panel comprises a plurality of tubular portions that are hollow inside to reduce weight. The tubular portions have an upper wall comprising pairs of parallel channels which slideably receive at least one sliding bracket for securing the load to the trailer.

Abstract: An improved side rail structure is used to form a portion of a flat bed trailer. The side rail structure is integrally formed as one piece. The side rail structure includes an outer side rail wall which is integrally formed as one piece with a rub rail. A flooring section may also be formed as one piece with the outer side rail wall. The one piece side rail structure may be formed of extruded metal.

Abstract: A bumper adapted for mounting to a trailer is provided. The bumper comprises a tail skirt extending horizontally across the rear of the trailer. Upright bars mount to and intersect the tail skirt. The tail skirt comprises a groove for receiving a recessed light bar comprising multiple signal lights. The wiring harness extends from the light bar into a space behind the upright bars and passes through openings in the tail skirt behind the upright bars.

Abstract: A trailer includes a floor engageable with a load and a longitudinally extending support member. The support member has an upper portion connected to the floor, a lower portion connectable to a suspension system, and a web extending between the upper and lower portions and transverse to the floor. The lower portion has a lower flange extending transverse to the web and connectable to the suspension system. The lower flange has a first portion extending from a first side of the web a first distance and a second portion extending from a second opposite side of the web a second distance larger than the first distance.

Abstract: A trailer includes a floor engageable with a load, the trailer floor comprising a plurality of floor panels. Each floor panel comprises a plurality of tubular portions that are hollow inside to reduce weight. The tubular portions have an upper wall comprising pairs of parallel channels which slideably receive at least one sliding bracket for securing the load to the trailer.

Abstract: A hanger assembly comprises a pair of hangers; a pair of trailer attachment plates, each attachment plate attached to one of the pair of hangers; and a transverse support member having a first end attached to one of the pair of hangers and a second end attached to the remaining hanger of the pair of hangers. The hanger assembly is made of aluminum and provides a lightweight, high strength hanger assembly for a trailer that cuts down on the weight of the trailer without diminishing the strength as compared to conventional trailers, and that is compatible with a conventional air ride suspension system and retrofittable on existing aluminum trailers in a bolt-on configuration.

Abstract: A hook hanger for a cargo trailer includes a body. The body includes: (i) a mounting bracket conforming in shape to and slidably engageable with an associated sliding track of an associated cargo trailer; (ii) a hook anchor connected to the mounting bracket; and, (iii) a wall that cooperates with the hook anchor to define a channel including an opening in a side of the body. The wall limits vertical movement of a hook connected to the hook anchor to prevent inadvertent disengagement by vertical movement. The hook is disengageable from the hook anchor only by sliding movement transverse to vertical and through the channel opening. The channel opening is selectively blocked by a movable leg member connected to the body.

Abstract: A hook hanger for a cargo trailer includes a body defining (i) a mounting bracket conforming in shape to and slidably engageable with an associated sliding winch track of an associated cargo trailer; (ii) a hook anchor connected to the mounting bracket; and, (iii) a wall that cooperates with the hook anchor to define a channel between the wall and the hook anchor. The channel opens in a side of the body, and the wall limits vertical movement of an associated hook connected to the hook anchor to prevent inadvertent disengagement by vertical movement of the associated hook from the hook anchor. The associated hook is disengageable from the hook anchor only by sliding movement in the channel in a direction transverse to vertical. A retaining member is optionally connected to the body and movable to a locked position where it captures the associated hook in the channel.

Abstract: Retroreflective sheeting or tape suitable for the sides of tractor-trailers comprises alternating red and white colors separated by customized areas of sheeting or tape of predetermined locations and length. The customized areas may or may not comprise a retroreflective surface. Preferably, the retroreflective sheeting complies with all United States regulations on conspicuity systems for the sides of tractor-trailers, including box trailers, flatbed trailers, tankers, and the like.

Abstract: A lightweight, high strength, one-piece subframe and suspension for a trailer that cuts down on the weight of the trailer without diminishing the strength as compared to conventional trailers, and that is compatible with a conventional air ride suspension system. The invention comprises at least two beams positioned generally parallel to each other; a plurality of ribs attached to the at least two beams and positioned extending transverse between and generally perpendicular to the at least two beams; at least one hanger attached to each beam; and wherein the trailer suspension subframe is made of aluminum.
